Clutch Snatching

[AMCQ46]

Why would you want to stop snatch clutching oh strange Celtic one?

Apparently there is a time and place.........although I have no idea what that means

[lloydie]

Have you any updates on this tony ?
Has it fix it ?

[tony.mon]

AH.
Well.
Mine doesn't do it at the moment, but then I haven't been to a drag strip, and it wasn't doing it on the road anyway, as I'd put on a clutch basket with almost no wear marks, so that doesn't prove much.

I'm awaiting another set of magic washers, which will be fitted to a member's bike that does it all the time, and with nothing else changed; that should be a fair test.

But I'm away for a week in Belgium from BH monday to the following Fri, so won't get much of a chance to fit them for a week or two.

Updates will surely follow.....Hopefully before the BSB Assen trip.

Tony if this is the answer its f***king genius as I want mine sorted as im fed up with pull-away roulette.

Couldn't see any mate thankfully , it would have been a good idea for Honda to mabe fit washers that had turned over edges or a lip or flange don't know the word I'm looking for but basicaly to stop those springs from slipping of there center axis

Yeh its spot on now tony no slip no grab , from the short run up the estate anyway, will report back if there are any issues, bled the clutch as well.

I don't know what you'd call them either, but some are heading my way this weekend for evaluation. If they work I'll let you all know.

Good it's sorted, see you on the drag strip then.

Bloody hell they took a while to turn up mate, that post was 1st june on me clutch thread lol

Yeah, money has been getting in the way of development work- or lack of it, actually...

Anyway, the dished washers have been fitted to three bikes now, and in a nutshell, it hasn't fixed the problem.
The clutch still grabs, less so in my case and Lloydie's bikes, but Duffy reports that his felt the same.

So it's still an ongoing problem, and therefore I've had to start digging a little deeper.

Honda rarely make a part that fits one bike only; they raid the parts bin over and over again, why re-invent the wheel etc.
So I looked at the clutch parts to see which components are used on other bikes, with the intention of seeing if they, too, had a clutch grab problem.
But most of the larger clutch parts on the VTR, the clutch basket, centre, pressure plate, for example, are used only on this model. I can understand that; the vee-twin configuration means that the layout of key components will be different, and the architechture of the clutch basket, size of gear in the primary drive, anti-rattle gear, etc are designed for just this model.
Yet they're still designed by honda, who have a lot of experience of these things; and I can't see anything that's likely to cause a problem.
Some parts, such as the "top hat" section that fits on the end of the clutch pushrod, fit lots of bikes- ST1300, VFR800, VT1100, and so I can rule that part out of the equation. If it can cope with clutch action on those bikes, it can cope with the VTR's output as well.

The anti-judder spring is also used on a number of bikes- CBR600, CB400, CB750, CBNR600F, CB1000. So we can rule that out of being the cause of the problem, too.

But interestingly, the anti-judder spring seat is once more a unique part to Storms. I wonder if they're different thicknesses?

I have two more things to try before that option:

1. Just to completely eliminate the possibility of clutch spring wearing grooves in the clutch components and "jumping " into the grooves, causing the problem, I have some steel chromed tube that fits neatly over the spring post (where the spring bolt and modified dished washer bolts into) and will definitely prevent to spring from being able to jump into those grooves.
I suspect it will rattle like a bucket of bolt in an earthquake, but it's fairly easy to try.

2. refitting the cable clutch conversion I made up a while ago, and took off so that I could try the dished washers.

If those don't work, I'll try to find an assortment of anti-judder spring seats and see if thicker or thinner makes any difference.

Thnaks to the two owners for volunteering their bikes in the name of research; they each saved 22 grams of rotating mass and will therefore be faster and get better fuel economy as a result.
I have two more sets of dished washers to offer for trial purposes if anyone wants them?
Obviously these need to go to bikes that actually DO have a clutch snatching problem, as it's no trial otherwise.

Ere Mr Dealer man , can you sort me out with a little Titanium? I'm cutting down, honest. Just a little hit is all I need! The bike ain't snatching but i'me clacking!

[lloydie]

im only happy to help

kev l your a tart

[Kev L]

Yeah I know, and there's you completley Titanium or Carbon free!!!!!!

[VTRDark]

Oooh I don't know about carbon free. None of us are carbon free.

(:-})

[lloydie]

Yeah I know, and there's you completley Titanium or Carbon free!!!!!!

ive got a long way to catch up with you
im trying to locate some titanium fairing bolts atm

[AMCQ46]

Tony,
Shame the fix didnt work, I had high hopes for it because it made sense

I need to take my new [to me, taken out of my spare engine] clutch out and look at it as it has developed a new and very annoying problem.........it is has started to become too progressive when I "pop the clutch" to lift the front wheel up
it isnt sliping in normal use, and it has started to grab a bit if i try and do drag starts, but I can live with that.... but the fact I cant wheelie anymore is embarassing

Thanks Tony I can now have that extra pasty and it will make the fast yellow storm even faster
Still a good effort matey, well worth a go to cure the pogo storm, sure yo will crack it soon and was only too willing to help donate my flying banana for the trial

Hi Tony,
My race bike is a pig to get off the line smoothly, I have almost looped it due to the grabby clutch, can I try a set of those washers and fit them for next season?
